I am a senior scientist (Director of Research) in Reproductive and Developmental Animal Biology at INRAE, the National Research Institute for Agriculture, Alimentation and Environment in France. My research focusses are mainly on sex determination and gonad differentiation in mammals with a particular attention to farm mammals (ruminants, pigs and rabbits). During the last decade, I have used the new technology of genome editing to decipher and demonstrate the role of sex-determining genes and their different functions between mouse and farm mammals. I have published over 80 papers and I am a member of the editorial board of the journal “Sexual Development”. I started to build the RUMIGEN project in January 2019 with three other scientists (Drs D. Boichard, J-L Vilotte & L Schibler) located at the same INRAE center of Jouy en Josas near Paris. At the same time, I accepted to be the coordinator of RUMIGEN, contributed to the writing of the proposal and now part of my job is to ensure that the project runs smoothly. Anne Jarousse from INRAE-Transfert nicely assists me on this task. In addition to this coordination, I am involved with different colleagues of my BREED unit (Biology of Reproduction, Environment, Epigenetic and Development) and of ALLICE society in different parts of the RUMIGEN project, mainly focused on epigenetic and potential new breeding technics.
